01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第29题(顺位题号是118)。给定非负整数numRows,生成Pascal三角形的第一个numRows。例如: 输入: 5 输出: [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 本次解题使用的开发工具是eclipse,jdk使用的版本是1.8,环境是win7 64位系...
publicclassPascalTriangle{publicstaticvoidmain(String[]args){// 创建一个10行10列的二维数组int[][]triangle=newint[10][10];// 遍历每一行for(inti=0;i<10;i++){// 遍历每一行中的每一个元素for(intj=0;j<=i;j++){// 第一列和对角线上的元素为1if(j==0||j==i){triangle[i][j]=1;}...
}for(intin: result) { list.add(in); }returnlist; } 05 验证与测试 针对上面三种解法,选取部分随机数字并测试不同解法耗时,代码如下: publicstaticvoidmain(String[] args){ Easy_119_PascalTriangleII instance =newEasy_119_PascalTriangleII();introwIndex =3;longstart = System.nanoTime(); List<Int...
Given a non-negative integer numRows, generate the first numRows of Pascal's triangle. 1. In Pascal's triangle, each number is the sum of the two numbers directly above it. Example: Input: 5 Output: [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 1. 2. 3. 4...

In Europe, Pascal (1623-1662) discovered this law in 1654, so this table is also called Pascal's triangle. Pascal’s discovery was 393 years later than Yang Hui and 600 years later than Jia Xian. 6. Find the greatest common divisor and the least common multiple...
